You're talking about the plane that belongs to the state department and was supposed to be for anti-drug use, right? I haven't heard a word about it since the story showed up just after the Stevens infection hit the press. I thought it an intesting coincidence of timing, but would have only given a few days' incubation period.
But I just found this:

I couldn't find any reports of it being found.
So, did Osama call in a favor on a drug-lord friend somewhere near the Bahamas to stash it away for a while, or did it really go down in bad weather? My bet is with the latter.
